ISBN: 978-86-7031-355-2 ii Preface This volume contains papers presented at the Sixth Workshop on Software Quality Analysis, Monitoring, Improvement, and Applications (SQAMIA 2017). SQAMIA 2017 was held during September 11 – 13, 2017., at the Hotel Prag, Belgrade, Serbia. SQAMIA 2017 continued the tradition of successful SQAMIA workshops previously held in Novi Sad, Serbia (in 2012 and 2013), Lovran, Croatia (2014), Maribor, Slovenia (2015) and Budapest, Hungary (2016). The first SQAMIA workshop was organized within the 5th Balkan Conference in Informatics (BCI 2012). In 2013, SQAMIA became a standalone event intended to be an annual gathering of researchers and practitioners in the field of software quality. The main objective of the SQAMIA series of workshops is to provide a forum for presentation, discussion and dissemination of the latest scientific achievements in the area of software quality, and to promote and improve interaction and collaboration among scientists and young researchers from the region and beyond. The workshop especially welcomes position papers, papers describing work in progress, tool demonstration papers, technical reports, and papers designed to provoke debate on present knowledge, open questions, and future research trends in software quality. The SQAMIA 2017 workshop consisted of regular sessions with technical contributions reviewed and selected by an international program committee, as well as two invited talks by Nuno Antunes and Stéphane Ducasse. In total 19 papers were accepted and published in this proceedings volume. All published papers were at least double reviewed, and in some cases even quadruple reviewed. We are grateful to all PC members for submitting careful and timely opinions on the papers. Our special thanks are also addressed to the members of the SQAMIA Initiative (sqamia.org) without who this and previous workshops could not be possible: Zoran Budimac (Novi Sad, Serbia), Tihana Galinac Grbac (Rijeka, Croatia), Marjan Heričko (Maribor, Slovenia), Zoltán Horváth (Budapest, Hungary) and Hannu Jaakkola (Pori, Finland) We extend special thanks to the SQAMIA 2017 Organizing Committee from the Department of Mathematics and Informatics, Faculty of Sciences, University of Novi Sad, especially to the two co-chairs Nataša Sukur and Tijana Vislavski for their hard work and dedication to make this workshop the best it can be. Further we’d like to thank Doni Pracner for his patience and diligent work on making the proceedings. This workshop is endorsed by COST action IC1402 Runtime verification beyond monitoring (ARVI). And last, but not least, we thank all the participants of SQAMIA 2017 for their contributions that made all the work that went into SQAMIA 2017 worthwhile.

How to derive software metrics thresholds is a topic of many researchers, either proposing new approaches, or verifying existing methods on different practical projects. A literature review was conducted to summarise the available knowledge in this area. The aim was to find approaches for software metric threshold derivation and extract relevant information, such as programming language for which an approach was proposed and tested, what metrics were derived, and if approaches are automated with supporting tools. Data extracted from 14 primary studies reveal that the majority of studies present new approaches and approaches usually apply statistical analysis for threshold derivation. Primary programming language for which metrics are derived is Java, followed by C, C++ and C#. We also came across some tools used for threshold derivation, but in practise their use was not detected. Metrics derived, purpose of metrics derivation and other information are also summarised in the tables bellow.

INTRODUCTION To deliver software product in required quality, it is crucial to address and manage the quality assur- ance domain properly. Software metrics can be used for reflection of the qualitative characteristics of software modules in a quantitative way [Arar and Ayan 2016], presenting a control instrument in a software development and maintenance process [Alves et al. 2010]. Software metrics assess software from different views and, therefore,
